• Examine the case before you use the Product. Look for cracks or
missing plastic. Carefully look at the insulation around the
terminals.
• Do not use test leads if they are damaged. Examine the test leads
for damaged insulation and measure a known voltage.
• Do not use and disable the Product if it is damaged.
• Do not use the Product around explosive gas, vapor, or in damp
or wet environments.
• Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.
• Do not apply more than the rated voltage, between the terminals
or between each terminal and earth ground.
• Do not connect directly to mains.
• Do not exceed the Measurement Category (CAT) rating of the
lowest rated individual component of a Product, probe, or

Calibration Adjustment Procedure

Calibration Adjustment Procedure

The Product features electronic calibration. There are no mechanical adjustments and
calibration adjustment is done with its case closed. The calibration adjustment is done
with the keypad. Use the display to guide you through the calibration process.
Note
Make sure that the Product has new batteries before you start the
calibration adjustment procedure. Calibration adjustment will not function
properly if the low battery indicator is on.
The calibration adjustment of the Product consists of three independently-calibrated
ranges: mA source, mA measure, and voltage measure. To enter calibration mode, hold
 and  down as you turn on the Product. The first mode to be calibrated is mA
measure.
Use the test equipment listed in Table 2 for calibration. If the equipment listed in the
Table 2 is not available, then equipment with the same or better specifications can be
substituted.
mA Measure Mode
To calibrate the mA measure mode:
1. Use the double banana jack cable to attach the current output of the Calibrator to the
jacks of the Product.
2. Hold  and  down as you turn on the Product to enter calibration mode. The
display should show:

hid001.eps

3. Output 0 mA from the Calibrator. After the output is stable, push the knob to
continue. As the Product takes readings, the screen shows ------- . When the readings
are complete, the screen should look as shown below.

hid002.eps

continue. As the Product takes readings, the screen shows ------- . When the readings
are complete, the unit goes to the check mode.

hid003.eps

5. The Check mode shows what the measurement will be with the new calibration
constants. Current can be sourced or not. No input is necessary. When finished with
the check mode, push the knob to continue to the next calibration mode.
mA Source
To calibrate the mA Source mode:
1. Use the double banana jack cable to attach the current input of the DMM to the jacks
of the Product.
2. Set the DMM to measure dc current.
3. After you have made your connections, the display should look as shown below.

hid004.eps

4. Turn the knob on the Product to adjust the display until it shows the same as the
DMM. After the output has become stable, push and hold the knob to continue. The
screen should look as shown below.

the readings are complete, the Product will go to the check mode.

hid006.eps

6. When you are done with the check mode, push the knob to continue to the next
calibration point.
Voltage Measure
To calibrate the Voltage Measure mode:
1. Use the double banana jack cable to attach the current output of the Calibrator to the
voltage jacks of the Product.
2. After you have made the connections, if you are in voltage measure calibration mode,
the display should look as shown below.

3. Output 0 V from the Calibrator. After the output has become stable, push the knob to
continue. As the unit takes readings, the screen shows ------- .
4. Output 30 V from the Calibrator. After the output has become stable, push the knob
to continue. As the Product takes readings, the screen shows ------- . When the
readings are complete, the Product exits calibration mode and goes to volts mode.
